Would love to say dibs, but I think this was the shorter of the two and I would really be better off witht he longer version.


This should weigh around 220g

sorry to hijack, is there much difference between UN54 LX, UN72 XT and UN91 XTR, it's the bearings?

Just weighed it on my Woolworths 'Value' scales :roll: and 220g seems spot on.

The weight is pretty much what differs between the 3 BB's you mention.

I doubt the bearings would have changed, just the casing and axle.

I think the bearing are actually caged types and not the sealed types you would assume. The whole lot is sealed though.
Guess someone could crack one open and find out.
